70 PROCEKDINGS OF THE MALACOLOGICAL SOCIETY. 



Hah. — Lagari, British East Africa, 



Allied to S. Mamhoiensis, Smith, but smaller, with shorter and 

 more convex whorls, and sculptured with spiral striae upon the last 

 three or four whorls, a character which is absent in that species. As in 

 Mamhoiensis, the periostracum here and there is indistinctly streaked 

 with brown. The lines of growth are rather stronger just below the 

 suture than upon the rest of the surface of the whorls, and have 

 almost a puckered appearance.
